Simple steps to prevent photoaging and sun damage:
1. Broad spectrum sunscreens with titanium oxide or zinc oxide with 30 or higher SPF are best.
2. Overapplication of liquid sunscreen, not sprays, including sides of the ears, front and back of the neck, face, arms, and hands or any other part exposed to the sun.
3. New powder sunscreens are easy to apply and can even be applied over makeup. It can be used twice if exposure to the sun is more.
A common misconception is that using multiple products with sunscreens, such as a moisturizer and makeup, provides double the protection, which isn’t true. In fact, some sunscreen ingredients can deactivate others.
There is scientific evidence that certain supplements may help to decrease the effects of UV radiation on the skin. Niacinamide, Vitamin B3, can be taken twice a day and is considered to be safe at doses of 500 mg. The retinoids can be used to treat the signs of photoaging. It is advisable that women who are pregnant or trying to get pregnant should consult the physician before using any sunscreen or nutritional supplement.
